/ 9 Claims. (01. ass-4.5

This invention relates to paper and cellophane bottles and is designed more especially as an improvement upon the structure disclosed in my co-pending application filed September 28, 1934,, Serial No. 745,981.

An object of the invention is to provide a container of this character which, after being filled, can be sealed so that the contents cannot be poured therefrom without breaking the seal.

It is a further object of the invention to provide a bottle or other container of paper or cellophane which has a pouring spout provided with a normally sealed closure, the opening through which the container is filled, being separate and distinct from this spout or pouring portion.

A still further object is to provide a container which can be made of any suitable shapes and sizes and which can be shipped in a perfectly sterile and sanitary condition so that the danger of contaminating the material being admitted thereto during the filling operation will be practically eliminated.

Another object is toprovide a container designed for holding milk, chocolate or other beverages where sanitary conditions are of primary importance, it being possible to fill the container with the ordinary filling machinery used for sup plying liquids, etc., to glass bottles.

With the foregoing and other objects in view 'which will appear as the description proceeds,

the invention consists of certain novel details of construction and combinations of parts herein= after more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings Figure l is a plan view of the bottle sealed following thefilling thereof.

Figure 2 is a front elevation thereof.

Figure 3 is an elevation of a portion of the container showing that part thereof opposite to Figure 2.

Figure 4 is a side elevation.

Figure 9 is a plan view of another form of container.

Figure 10 is an elevation of a. portion thereof.

Figure 11 is a plan view of another form oi container.

Figure 12 is an elevation of a portion thereof.

Figure 13 is an enlarged section through the upper portion of a container made without a. neck and showing a modified spout sealing anrangement.

Figure 14 is a plan view thereof showing a temporary sealing cap in position.

Referring to the figures by characters of reference, l designates the body of a paper container made up of a desired number of thicknesses of paper board or the like initially made cylindrical with a circular bottom closure 2 joined thereto in any manner desired. The top portion of this body l is pinched longitudinally to form a radially extended spout t ll-shaped at the top and gradually diminishing in transverse area toward the bottom of the container where it merges into the round contour of the container.

Applied to the top is a cap 5 of paper or the lib like of suitable strength shaped so as to fit snugly upon the container a little more than half oi which, when viewed from-the top, is a segment of a circle while the remainder is v-shaped as a clearly indicated in Figure i. This can has a depending flange 5 which laps the body 6 of the container and suitably affixed or otherwise joined thereto. That portion of the flange extending along the sides of the spout 3 adjacent to the point 6 thereof is divided from flange 5 as shown at i, this divided portion 8 oi the flange being fiimovably joined to the sides of the spout or else shaped to bear snugly thereagainst. By means of a sealing tape ii or the like extending across the spout portion of the cap 6 and afiixed to the sides of the spout, the cap can be held snugly on the spout so as to prevent escape of the contents of the container.

If desired the body i can be formed with a two surfaces of the spout 3 and flap II, due to this neck being of any desired proportions and having an enlarged mouth portion l3 providing a seat l4 for engagement by a sealing cap l5. This cap can be held in place by any suitable means after the filling ,operation and it is designed to so proportion the neck of the container as to allow the device to be filled by the use of ordinary 'filling machinery such as employed in the filling of glass bottles: If desired cap Hi can be sealed by any suitable means following the filling operation and, as a sanitary measure, an outer cap or covering l6 of cellophane or other suitable material can be placed over the filling opening so as to protect the same prior to the filling operation. It is designed to apply a temporary sterile cap by machine during the manufacture of the container immediately after each bottle comes out of the parafiining operation.

The foregoing operation is to keep the paper bottle 100% sterile from the time the bottle is finished and packed into the shipping cartons, to the time that the bottles are received at the dairies. When unpacking these bottles out of their respective cartons onto the conveyors, these temporary sterile caps [6 are pulled off each bottle and discarded, just before it goes into the filling machine to be filled with whatever liquid they are being used for, such as milk, chocolate, water, etc. It will be observed by this method of closing each' paper bottle manufactured with a temporary sterile cap, in the factory where the bottle is made, is a big advance toward a completely sanitary, sterile paper bottle, as the inside of the bottle as well as the filling neck portion, which contacts the filling tits on the filling machine, is not exposed to human touch at any time, and is exposed to the atmosphere in the filling room of the dairies, etc., for a few seconds only, from the time each bottle is placed on the conveyor, until the conveyor in turn carries the bottles to the filling machine, where each bottle immediately after being filled through the filling opening, is sealed with another cap; thus sealing the filling hole or opening permanently.

The consumer on receiving a container breaks the seal 9 and pulls upwardly on the flap I! which will thus swing upwardly substantially on a line i 8 scored or otherwise defined and which connects the ends of the flange 8. Thus the contents can be poured out of thespout into a re- .ceiver and if only partly removed the remainder can be protected by closing the flap I1 down onto the open end of the spout 3. It is to be observed that this flap l1 will stay closed on its own accord, because of the friction created between the the snug fit, by means of the fianges 8 on the fiap ll over the spout 3 at the top.

In Figure 6 the structure thus far described has been shown slightly modified with the fiange IQ of cap 20 extended downwardly into and secured to the container body I while the flange 8 of the fiap l1 remains unchanged and upon the outside of the container body.

Bottles of all shapes, sizes and materials embodying the present improvements can be made without neck portions and the filling openings can be provided in the fiat tops as shown for example in Figures 13 and 14. In Figure 13 is shown a sealing cap 2| seated and sealed in a depression 22 after the container has been filled and which is substantiallyfiush with the top.

To provide a temporary sterile cap for this modified arrangement prior .to filling, a temporary sterile cap 2| will be used as shown in Figure 14. This is made up of a very light and thin inexpensive stamped-out circular cap, provided with a pre-semi-punched, depressed portion 2 l so that when given a slight pressure with ones finger, it will open a hole of suiilcient size for a man to insert a finger and pull out of the bottle this temporary sterile cap, and then to be discarded.

In Figures 13 and 14 the flap over the spout has been shown held by a seal 23 fitted across or bridging the angle portion of the spout and flap. This arrangement can also be used on any or all of the other forms shown.

As shown in Figures 7 to 12 inclusive the container can be made of shapes other than that already described. Not all of the additional shapes have been shown but it is to be understood that other shapes can also be made without departing from the present invention.

As illustrated in Figures 7 and 8 the body portion of the container can be made in the shape of a pyramid frustum, this body portion 24 being closed at the bottom and at the top by rectangular caps 25 and 26 respectively. These caps can be joined to the body portion as heretofore explained and the top cap can be formed with a projecting neck 28 having a filling opening to be sealed by a cap 29 as heretofore explained. One corner portion of the cap 26 forms a sealing flap 30 similar to the flap l1 and having flanges 3i lapping the outer sides of the container and separated from the fianges of the cap 28. Flap 30 can be held closed by a breakable seal 32 or 23.

In Figure 9 a cylindrical container 33 has been shown, the same being provided with a circular cap 34 at the top thereof on which is formed or secured a triangular extension 35. This extension in turn is closed at the top by a triangular cap 36 one corner portion of which constitutes a sealing flap 3! corresponding with the flaps I1 and 30 and held closed by a seal 38 or 23. Extension has a neck 39 extending therefrom with a filling opening adapted to be closed by a disk or cap 40 such as heretofore described.

Instead of providing a cylindrical body or a body of any other shape with a triangular extension 35, the entire body portion of the container can be made triangular as shown at 4i in Figures 11 and 12. In this structure the top cap is also triangular as shown at'42 and held to the body portion as heretofore explained. One corner portion of this cap 42 forms a sealing fiap 43 and is held closed by a breakable seal 44 or 23. A cylindrical neck portion 45 is extended from cap 42 and is adapted to be closed by a disk or cap 46.

In all forms of the device it is preferred to provide a transparent window such as has already been described with reference to Figures 1 to 4 inclusive, the windows in the modified constructions being indicated at 41 and 48 respectively.

It will be noted that in all of the modified structures the corner portions normally closed by the sealing flaps constitute the pouring spouts whereby after a fiap has been torn from closed position and pressed open, the contents of the container can be'poured in a comparatively narrow stream.

It is to be observed that the seal-cap protects the lip or pouring spout against contamination from human touch at all times, due to the fact that the side flanges 8 of the flap I! always keeps the pouring spout covered and therefore never exposed to any contamination or unsanitary handling. In other words, this protected part of the spout positively cannot be touched by human hands before the seal is broken. Even after the seal is broken, the only time this protected portion of the spout could be touched is when flap I1 is lifted up and then deliberately touched.

Where the containers are made of sheet material it is preferred to locate the edges of the material at or adjacent to the spout or outlet portion of the container as has been indicated at 49 and 50 in the several views. Thus the spout portion is reinforced in the direction of its length and will not be so easily dented or pressed inwardly should the container be allowed to bear downwardly at its spout portion upon a cup or other receptacle into which the contents are being poured.

It is to be understood that any or all forms of the bottle constituting this invention can each be made of cellophane or other suitable transparent sheet material instead of paper. Obviously the cellophane bottle when completely finished will not be subjected to the paraflin process as all the joints for the bottoms and tops will be thoroughly cemented to the body of the bottle. The general constructions of these bottles are to be similar to and along the same lines as covered in my co-pending application filed September 28, 1934,. Serial No. 745,981 and also following the same construction shown herein.

The cellophane bottles will be made in sizes ranging from one-half pints up to and including live gallon water bottles, the larger capacity bottles being made from a trifle heavier gauge cellophane stock.
